MEANS FOR CONTROLLING THE TRAVERSE OF YARN GUIDES ON SPINNINGMACHINES.

Application filed December 7, 1921. SerialNo. 520,626.

To all whom it may concern Be it known that I, EDWARD E. NOWELL, a citizen of the United States, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Means for Controlling the Traverse of Yarn Guides on Spinning Machines, ofwhich the following is a specification, reference being had to the accompanying drawings.

This invention relates to spinning machinery and particularly to means for winding yarn upon a bobbin or yarn receiver in such manner that a preliminary winding or bunch is first laid and then a main or surface winding is laid, the bobbins or cops so wound being used in the shuttles of automatic feeler-replenishing or feeler looms.

The general object of my invention is to provide improved means for automatically changing from bunch winding to surface winding and automatically varying the length of the traverse during such winding.

Another and more special object is to simlify the mechanism for this purpose and render it very compact so that it shall be relatively cheap to manufacture and install and shall take up very little room.

A further object is to provide a controlling mechanism of this character which shall be capable of being applied to a large variety of spinning machinery and whichmay be used with any ordinary builder action and with any ordinary ring rail lifting mechanism.

. Still another object is to provide a mechanism in which the length of the traverse for forming the bunch may be easily varied.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Fi ure 1 is a front view of a portion of a spinning machine having my invention applied thereto;

Figure 2 is a section at right angles to .Fi 'ure 1. showing the builder action;

Figure 3 is an elevation partly in section of a portion of the builder action and the members 27 and 34; 1 V

Figure 6 is an elevation showing the ac-- tion of the device when the member 34 is shifted;

Figure 7 is a vertical sectional of the spindles B; and

Figure 8 is a perspective view of the screw pin 39.

Figure 9, is a fragmentary view showing pin 39 in operative position. Referring to these figures A designates the view of one spindle rail supported on a suitable frame and on which are mounted the rotatable spindles B. Coacting with these spindles is the reciprocating ring rail C provided with rings D, one for each spindle. These rings are reciprocated by means'of lifter rods F which engage with the ring rail and these lift-er rods are operated by means of the rocker arms Gr which are angular in form to provide the upwardly extending arm these arms being connected bya rod I in the usual manner and being pivoted each upon a pivot J and being each counterbalanced by a weighted'arm K. All of these parts may be of any-ordinary or suitable construction. At theupper end of one of the arms H are'disposed the bolts 10 having hooks at their extremities, these bolts being adjustablethrough the arm H.

For the'purpose of oscillating the rocker arms G and H to therebycause the reciprocation of-the ring rail, any ordinary builder action is used, and I have illustrated in Figure 2 a common form ofsuch action, in i which 11 isthe'builder arm which is piv 'oted at 12 and which carries at its inner end a drum 13. This drum is rotated in one direction by means ofa worm 14 mounted upon a pick shaft 15 which carries upon it a pick wheel 16 adapted to beturned upon the upward movement of the inner end of the armby means of a pawl 17 and the usual vertically disposed rod 18 Y which passes through the frame'of the machine and which is provided with a stop 19 which, when it engages the frame, depresses the outer end of the pawl and turns the pick wheel a predetermined amount to rotate the drum 13 in I an unwinding direction. The builder arm 11 is oscillated by means of a cam 20' of any 1 suitable or usual form. 7 All .of thesefparts are those commonly found in spinning machines of th1s character.

Mounted in a suitable bracket 21 attached to the frame is a shaft22 which is preferably "fixedly mounted in the bracket. Loosely mounted [$3011 this shaft is a ear wheel 23 l as i and mounted and held-from rotation on this shaft isa disk 2%.

The gear wheel '23 has upon its face controntingvthe disk 2 a plurality of ratchet t'eeth 25' andthe disk 2 carries ajplurality of coasting ratchet teeth 26. The'teeth 25 and26 togetherconstitute a ratchet clutch. VSurrounding the gear 23 and the disk 24. is a *c rum designated gencrally 27 which is formed-in two sections.

This drum is mounted to rotate with the V shaft 22. A spring 28 surrounding the shaft 22 ur 'esfth e ear wheel 23 toward the disk 2% so as to bring the clutch teeth 25 and 26 into engagement with each other. The section 29ot'the drum is provided adjacent one point of its'p'eriphery with a-passage in which is disposed a shatt 30, the inner exv tremity of this shaft being supported in a bearin il formed in the 03 osite section of the drum. This shaft, at one point in its Y len th is formed with ear teeth 32 meshin a, 7 h h with'the teeth on the gear wheel 23.. The

outer end of the shaft is: formed with a socket 33 which is interiorlyscrew-threaded as at 33 V Loosely mounted upon the shaft 22 exteriorly of the section 290i the drum is a segmental disk 34-. This disk is itoi'med with' the circuinterentialtaco 35 and the end faces 'an'd37jwhichare'disposed at an angle to each-otherythese faces 36 and 37 extend;

inward convergently and intersecting the taCe-ZSS' ot thehub of this disk Carried upon the j disk 34 is a pin 39 whichprojects inward beyond the inner face ot the disk and is'provided upon one'portion of its periphery with a plurality of; interrupted screw threads 40 adapted to 'be engaged by the screw threads 33 'This pin is engaged I withthe disk3 hin such manner that the disk and pin-willunoretogether; I have illustratedthepin as being connected to the 7 'disk by transverse P111; As before re .(l'lillKOfl the disk v isloose upon the shaft'22, but is urged toward'the drum by means of a coilspringr 41,0119; end of which is engaged witht-he disk 3 L while the other end is engaged witlrthe collar 42 nstably mounted" upon the shaft 22. I

Extending? around therefrom is a chain which e'stends V ward andpartly-a ound thediiuin 2? the extremity'oi' the chain being connected to the drum by means ot the screw 44, v. littajehed toithe'drinn 27 by means of? ascrew 451s a chain &6: which extends around the drum and then-extends to and is operatively en'- gagedwit-11 0115012 the hooks l0. Attached to one end of the disk 3i bynmeans of a screw 47 is achain 48 which pass'es aroun'd the circular circumference of the disk, then extends a-long'the face-'3'Zover the hub 38' any suitable character.

7 the i drum 13 and adapted to be wound up tl ereon or released and then tangentially to the other hook 10,

j the chains 46ande8 being connected to these 7 hooks by means of rings 'or shackles "49 of The disk orfmember 34 is normally disposed in the position illustrated in Figure land Figure 3 and undertheseconditions P the chain 48 is taut While the chain 46 is slack. Now it will e-obvious that motion communicated tothe oscillating drum 27 will also be communicatedto the disk 34,

by reason oi? the fact that the pin '39 is engaged with the drum. Inasmuch as the chain a8 is at this time taut, it will-be obvious that motion will'be transmitted to the rocker arms H by means of the-chain 4L8,'and

it will be also seen that asthe endot this v chain 48 moves in a-path nearly parallel to vthe direction of the upwardly extending arm's H ofL-the rocker arms; but a very s5 small motion of oscillation will be given to i the rocker arms and this will continue so long as the disk 34 is positioned as illustrated in Figure 3 Upon the upward move} ment of the builder arm, the drum 2? will rotate in a clockwise direction. The gear wheel 23 being, in mesh with the gearteeth,

on shait32, it followsthat this gear wheel 23 will rotate with the'drum by. reason of, r

the pressure of the spring 28 and its clutch teeth 25 will slip by the clutch teeth 26; Upon a. reverse movement otthe drum 37, howeveijthe gear wheel 23 will be held from reverse rotative movement by -the engagement of its clutch teeth 25 with theteeth ofthfe' fixed clutch 24, and as a consequence cause a rotation of the shaft 30.

to shift the pin 39 outward and with the pin the disk 34 againstthe action of the spring 41." Thus upon each oscillation of the drum" 7 the segmental memher 3t and the pin '39,"

which is fixed in the segmental memben will move outward against the torceofspring' 4:1 and eventually the pin 39 will he forced out of and disengaged from' the screw threads 33, whereupon thegspringg ell will cause disk 34 torotatefrom the position shown in Figure 3 tO tlieposition shown in Figure 6, that is with the face 37 of the i disk 34' extendmg approximately" vertically and the corner 05 of the'meinher 3twillihe c coincident with the uppermost portion of the drum. 'This'rotationot the member 34 will "slacken the'chain 48 so'thatiwthis chain or flexible connection 48 will he thrown out ot' atcion and the motion of drum 37 willj be i onnn'unicated to the 'chain LG'and the' oeker I The socket-33 1s interiorlyscrew-threaded and the'pin se-has' a coacting screw-thread,

and as socket 33 revolves itrwill" push the pin 39'a-nd disk 34 outward'against the force of spring 41, and when the pin 39flhas;

The pin 39.is threadedionly bathe: side and the": ason forth-is is that if it were threaded on all sides it would engagewith the threads "of the sockehwhen thepin is being again inserted in the threaded socket The diameter of thepin39 from the threaded side to the plain side'is just small enough to permit the pin 39'to slip into the socket without interfering wi'th the threads thereof. At this time the plain side of the pin is against the threads, as will appear more fully hereinafter. Then as the frame is being started up after being dotted, the chain 46 will act to rotate the disk 27 and this will shift the disk 27 relative to the sector-shaped member 34 aldistance equal to the difference betweenthe diameters of the pin 39 and the screw-threaded socket 40, and this will bring the threads of the socket against the threads ofthe pin 39 and the pin will/once more be in engagement with the threads on disk 34 and. cause the threaded side of pin 39 to engage with the upper threaded side of the socket.

In Figure 7.1 show a bobbin or yarn receiver 50 of a well knownform, This has an enlarged base i and an aproximately cylindrical but tapering barrel. Near the head the barrel is made cylindrical to receive the preliminary winding or bunch of yarn. The preliminary winding or bunch a "is laid upon this cylindrical portion to the extentillustrated in'Figure 7' and thereafter the win ding is completed by the main or surface'winding indicated by dott'ed lines. The mechanism heretofore described is arranged to wind such a bunch and thereafter to lay the main or surface winding, the *change from the bunch laying to the surface winding laying being automatic. The traverse is uniform during the winding of the bunch and "uniform during the laying of the main winding,but the traveres'is considerably shorter while'the bunch is being laid than while the main winding is being laid, as is well under.-

stoodby those skilled in the art. The gain of the traverse is affected by the operation of the'drum l3fthe pick wheel 16 and the pawl 17in the usual and well known manner.

The operation of the invention istis follows: Bet the start of the" winding, the member Figule 4. and the pin 39'isffully inserted within'the socketl33fi /Viththe member34 in the position shown in Figure 3, the chain 1 i r motion communicatedt'othelrocker arm must come throu h the chain '48. It Wlll.

tica'lly the point of. attachment or the chain 48 at this time and that the-member 34 con-.

' the segmental I g V key 34. however, is in the position lllustr'ated 1n- 43 is taut but the chain 461's Slackso'that seen that the corner 'az co'nstitutes pra stitutes practically an arm extending in a cirectiojnl transverse to the direction of reciprocation of the lifter rods F. As a con sequence, when the member 34 is oscillated by the oscillation of the drum through the action of the builder action, the corner will move toward and from the rocker arm l-l a relatively small amount so that a .relatively short oscillation will be given to the rocker arms ll. Step by step asthese; oscillations continue, the screw 39 will beshifted out until eventually it is disengaged from the socket 33 and at thistime the hunch is completed. When the pin39 has worked out from the socket the segmental disk 34 will move so that the pin'39 will be carried up slightly away from the socket. This slight movement of this segmental disk in the. direction .of the arrow (Figure 3) will slacken the chain 48 and as this chain no longer limits the oscillation of the arm the chain will no longer remain slack upon a clockwise movement of thedrum 27 but will permit the rocker arms to shift to a greater range, thus increasing the traverse of the spinning rings and the ring rail. The pull on the chain 48 with the parts in the position shown in Figure 6 tends tohold the pin39 away from thesocket. The end of the pin 39, however, drags on the cover 29 during the filling of the bobbins.

The collar 42 is so set as to give" a twisting force on the segmental pulley or disk 34, while at the same time the spring urges pulley 34 or disk inward or toward the cover 29. When the bobbin has beencompletely wound and is to be dotted,

the ring rail is pulled down by the operator and, of; course, the lifting rod F and the rocker G move down and when this is being done'the vertical arm Hwvhich carries the chain hook 49 moves in the direction of the drum 27 and thus the chain's-3 movesdownward with the builder arm 11. This causes the drum or disk 2? to turn in the same direction as the chain 43, or n other words to.

turn in a counterclockwise direction. The

segmental pulley or disk 34 moves with the drum 2'? ,inthis direction, but not through "the action of the chain 43 but only through the twisting action of the spring 41. When the'builder arm hits the floor, the chain 43 becomes slack and the drum 27 or. disk does. not turn any further. The segmental pulturns; a little further through the action of thespring 41 until the pin 39 comes oppositethe'socket 33. When the pin 39' comes opposite the, socket,;thef

spri'ng 41 will urgethesegmental pulley V34'with the pinfixed thereto inward orito;

wardthe drum 2'? and the pin, of course,

will slip into the so'cketandl the parts are ready to repeat the-operation. When the "pin39 is being inserted into thesocket 33?,

thetwisting'action of the spring 41 keeps means resisting movement of the second named transmission member toward a neutral position, and means acting as the first named transmission member is oscillated to cause the pin to shift little by little out of the socket to thereby detach the transmission members from each other.
